Hi,
I checked the column names and the values. They are same as
they are in the table.
Do we need to install hive or add some hive libraries in hadoop's classpath on
the datanode-machines also. If yes then please guide me.
Thanks & Regards,
Aditya

Hi,
I am curious that if the 'value', for which we are looking for
in a column, doesn't exist, doesn't hive tells 'no data found matching the
criteria' or something like that, rather than returning an error.

Hi,
I have setup a two node hadoop cluster, and tested it by
running examples provided with Hadoop. Examples are working fine. then I tried
to run hive on the cluster. I was able to create tables and load data into
tables. And also the query : "select * from tablename" is working fine. But
when I try to run a query with where option :
hive> select * from tablename where column_name='Value';
I get the following error
Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.ExecDriver
The jobdetails.jsp shows the following:
java.lang.RuntimeException: java.util.NoSuchElementException
at org.apache.hadoop.hive.ql.exec.Utilities.getMapRedWork(Utilities.
java:168)
at
org.apache.hadoop.hive.ql.io.HiveInputFormat.init(HiveInputFormat.java:235)
at
org.apache.hadoop.hive.ql.io.HiveInputFormat.initColumnsNeeded(HiveInputForm
at.java:311)..............
............
I am using hive's derby only and not MySQL or any other DB for metastore. And
most of the settings are having their default values in Hadoop, except for the
minimum changes needed to run the cluster. There is no hive-site.xml as I
haven't changed any of the hive's properties.
Please tell me what is wrong and what do I need to do.
